Neutrophil serine proteases

Abstract

The identification and characterization of the four active neutrophil serine proteases (NSPs) have provided a better understanding of their roles in various physiological and pathological processes. The availability of appropriate tools such as substrates, inhibitors, and activity-based probes (ABPs) for studying their activity and functions in cells has become increasingly important. In this paper, the authors provide a comprehensive overview of the current state of knowledge on the tools available for studying NSPs. The substrates, inhibitors, and ABPs that have been developed to date are described, including their strengths and limitations. The authors also discuss the potential implications of these tools for future research on NSPs, including their potential use in the development of new therapeutics for various diseases. Overall, this paper highlights the importance of understanding the activity and functions of NSPs and provides valuable information on the tools available for studying these proteases.
